How To Disable PageUp and PageDown Keys on Windows 10

Solution 1:

Warning: this solution involves editing the registry.

Open regedit.exe and browse to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout\". Add a new binary key value and name it "Scancode Map" (if it already exists, just edit it to change the values which are not zeroes). Enter:

00 00 00 00 00 00 00 00
03 00 00 00 00 00 49 E0
00 00 51 E0 00 00 00 00

Reboot and the PgUp and PgDn keys should be disabled.

Cheers!

Solution 2:

This utility does the same thing as the registry edit in the answer from @johnbchron, but it adds a UI to make finding the correct key a little easier.
